Idempotency

Money-moving operations accept an optional Idempotency-Key header. Reusing the same key with the same payload returns the original result instead of creating duplicate charges.

When to use it

Generate a unique key per user intent (UUID recommended). Retries for the same intent should reuse the key.

Example

Send the request to {docsEnv.apiBaseUrl}:

Code
POST /CREATE_PAYMENT_LINK HTTP/1.1
Host: {docsEnv.apiHost}
Authorization: Bearer {docsEnv.keyPrefixExample}
Idempotency-Key: plink-intent-8f3c2a1b
Content-Type: application/json

{ "amount": 2500, "currency": "USD", "productName": "Consultation" }

Use Sandbox or test keys in this environment.
